SAFE, VAULT, &c.

Specification of Letters Patent.

Patented June 23, 1908.

Application filed February 18, 1905. Serial No. 246,327.

To all whom it may concern:

Be it known that I, ALEXANDER WILsoN MARR, a citizen of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Safes, Vaults, &c., of which the following is a specification.

This invention relates to that class of hinges or supports for the doors of safes, vaults and like structures in which the door is carried by a slide or block movable along a horizontal bar, forming the movable member of a twopart hinge, and the present invention consists in a novel form of bar, and supporting rollers for the block or carrier. The bar and rollers are applicable to this type of door supports generally, and without regard to other details of construction, but I have here represented the invention as applied to a supporting bar having a knucklejoint at a point between its ends, and adapted to swing outward through the doorway or the plate C,

opening and then break or fold to carry the way. This type of door particularly for the inner door well out of the support is intended doors of safes and front wall and two doors, the inner door being set well within the safe.

In such structures it is desirable to provide for bringing the inner door out through the front and swinging it laterally out of the way of the front opening.

In the accompanying drawings, Figure 1 is a horizontal section on the line l1 of Fig. 2, showing the front portion of a safe in out line, and the inner door and its hinge or support in full lines; Fig. 2, a vertical section on the line 2-2 of Fig. 1, showing the inner door and its wall in front elevation. Fig. 3, a view of a portion ofthe inner front wall, the door and its support on a larger scale and with portions broken away; Fig. 4, a transverse section on the line 44 of Fig. 3 Fig. 5, a detail of the bolt mechanism.

The general features of the hinge or door support are not herein claimed.

indicates a safe or vault of any usual or desired construction, here represented as having an outer and an inner front wall, each provided with a doorway.

B indicates a door or closure for the inner doorway, here shown as of circular form, though that is purely optional.

O indicates a hinge-plate or leaf, secured rigidly to the body of the safe, preferably to vaults having a double the inner front wall, and D, a second hinge member in the form ofa bar, pin-jointed to after the manner of a strap hinge.

Bar D is formed with a knuckle-joint a, at a point between its ends, and the knuckle is of such form as to permit it to buckleor break only in an outward direction, The bar is formed with -shaped upper and lower edges, as best shown in Fig. 4, and will advisably be formed of steel and tempered or made quite hard to withstand wear, but I do not restrict myself to any specific metal,

or to tempering thereof.

E indicates an upper and F a lower block of metal, each secured to the front of the safe door by two or more screws ortap-bolts G. These blocks are placed respectively above and below the bar D, and are connected one with the other by a metal strap or plate H, as seen in Figs. 2 and 3.

As shown in Fig. 4, in connection with the upper block and its fastening screw, the screw-hole is enlarged vertically so as to allow slight vertical adjustment of the block, this provision being made for all the screws of the upper and lower blocks alike. Passing vertically into the blocks from the upper side of the upper block and from the lower side of the lower'block, in alinement with the holes for thescrews or bolts G, are threaded holes to receive screws I. The screws I, which are quite substantial, bear at their inner ends against the shanks or' bodies of the screws or bolts G, and being suitably backed in one block and advanced in the other while the screws or bolts G are not quite turned to their seats, they serve to raise or lower the blocks, which being connected by the strap or plate H, move in unison. blocks can be nicely adjusted to take bearing upon the bar D when the door B is accurately seated or centered in the doorway. When the adjustment is, made the screwsor bolts G are turned home and thus made to clamp the blocks firmly to the face of the door".

As shown in Fig. 4, the blocks E and F are channeled in their proximate or opposing faces, to receive rollers J, which bear upon the V-edges of the bar and thus at once support and guide the door in its movements lengthwise of the bar.

It is important that there be no cramping or binding of the rollers upon the bar, such as would result were they provided with V- In this way the grooves of precisely the same angle as the edges of the bar. To guard against this undesirable condition, I form the rollers with grooves of the form shown in Fig. 4, that is to say, each roller is of the form that would be produced by placing the conveX- faces of two hemispheres in close contact, or joining them by a short spacing section. The convex faces bear upon the opposite faces of the V-edges of the bar much as balls or spheres would do, or, in other words, each roller bears at a single point only upon a given face of the V-edge on which it rests. By this arrangement there is avoided that rubbing and binding effect incident to the different radius of different portions of a common V-groove, and the consequently varying rate of rota tion in traversing the bar. This constitutes the chief feature of my invention.

The inner door is chiefly intended as a protection against fire and may or may not be furnished with a permutation lock or other fastening difficult of o ening except with a knowledge of the combination, or with the proper key, as the case may be. I have shown in Figs. 2 and 3 a well known form of bolt, in which the two bolt members or slides K and L are moved in reverse directions by a rocking or rotating tumbler l\ I, provided with a suitable hand-piece N. Any other suitable fastening may be provided.

In use, the door being unfastened, is drawn outward from its seat or opening and moved laterally, the rollers and thus permitting the door to move freely and with slight application of force. WVhen the bar D is swung outward to the position indicated by dotted lines in Fig. 1, the door is moved outward until strap or plate H encounters a stop 0, the blocks having then passed the knuckle-joint of the bar D. Then this is accomplished, the bar D is broken or buckled at the knuckle-joint, thereby carrying the door to the osition indicated in Fig. 1, where it is out o the way of those desiring to gain access to the interior of the safe.

It is apparent that the improved roller support may be used in other relations, and ience I mean to claim the same broadly and without restriction to the specific use or relation here indicated. Mere reversal I deem as comprehended within my invention.

J rolling along the bar D Having thus described my invention, I claim 1. In combination with a bar or sup ort having its upper edge formed with two p ane faces at an angle to each other and to the horizon; a block or carrier mounted thereon and provided with an anti-friction wheel or roller having two bearing faces of convex form in cross section, and at right angles to said bar, said convex faces bearing res ectively upon the respective inclined p ane faces of the bar, whereby any tendency of the block to rock or tilt laterally with reference to the bar is counteracted.

2. In combination with a bar or support, a

block or carrier supported by and movable relatively to said bar; and an interposed grooved anti-friction roller adapted to straddle the upper edge of the bar, the bearing faces of the bar and of the roller being respectively of plain and of convex form, substantially as shown and described, whereby the bearing contact of the roller on each face of the bar edge is reduced to a point, and the arts are caused tomaintain their proper reation at all times.

3. In combination with a bar D having substantially V-shaped upper and lower edges, a carrier mounted and movable u on said bar and rovided with grooved rol ers to straddle and traverse its edges, said rollers having convex bearing faces on opposite sides of each V-edge, substantially as shown and described.

4. In combination with a supporting bar having substantially V-shaped upper and lower edges, a carrier mounted and movable thereon, comprising blocks E and F, each provided with grooved rollers J, and a strap or plate connecting said blocks; a door or other object to be supported; screws or bolts G passing through enlarged holes in the blocks and into said door or other object; and adjusting screws I passing through the blocks and bearing upon the screws or bolts G, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALEXANDER WILSON MARK.
